ClGAR-BUNCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 42,278, dated December 9, 1890.

Application filed April 3, 1890- Serial No. 346,501. (No model.)

To all whom it 11-May concern:

Be it known that I, JOHN H. WILLIAMS, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Cigar-Bunching Machines, of which the following is a specification.

The invention relates to improvements in cigar-bunching machines, and particularly to machines for the manufacture of cigar bunches from long-filler tobacco.

The invention portainsparticularly to mechanism for automatically feeding the tobacco to the devices by which the separate charges thereof for the bunches are compressed and conveyed to the rolling mechanism whereby the bunch is formed.

The in vention will be fully understood from the detailed description herein afterpresentcd, reference being had to the accompanying drawings, in which Figure 1 is a front elevation of a cigarbunching machine having the invention applied thereto. Fig. 2 is a detached vertical section on the dotted line 2 2 of Fig. Fig. 3 is a top plan view of the feeding niechanism constituting the invention, the upper portion of the eigar-bunehing machine proper not being presented. Fig. 4 is a detached side elevation, on an enlarged scale, of certain gearing for transmitting motion hereinafter particularly referred to; Fig. 5, an enlarged vertical section on the dotted line 5 5 of Fig. 3, looking toward the buncl1ingmachine proper; Fig. 0, a vertical section on the dotted line 0 (3 of Fig. 3; Fig. 7,a vertical transverse section on the dotted line 7 7 of Fig. 3. Fig. 8 is a top plan view of the device illustrated in Fig. 7. Figs. 9 to 13,inclusive, illustrate, on an enlarged scale, means for controlling the supply of tobacco to the feed-trough, Fig. 9 being a side elevation of a part of said trough with the regulating devices applied thereto; Fig. 10, avertical section of the same on the dotted line 10 10 of Fig. 11, which is a top view of same. Figs. 12 and 13 are detached views of the face and edge, respectively, of a detached portion of the mechanism hereinafter specifically referred to. Fig. 14:

is a detached top View of the outer end of the feed-trough, illustrating the position of the leaves as theyare fed to the devices by which the separate charges are formed; Fig. 15, a central vertical longitudinal section of same; Fig. 16, a vertical transverse section through the machine at the point where the charges of tobacco are formed and pressed into the charge-receptacle, by which they are carried to the rolling mechanism, said view illustrating the position of the tobacco prior to the depression of the pressers, by'which it is forced into the charge-receptacle; Fig. 17, a like view of same, illustrating the position of the tobacco after the pressers have been, lowered and the charge forced into the charge-receptacle; and Fig. 18 is a like view of same, illustrating the position of the tobacco after the knife has severed that portion thereof within the receptacle from the surplus portion above said receptacle and beneath said pressers.

In the drawings forming apartof this application 1 have illustrated a cigar-bunching ma chine which, without the feeding mechanism which constitutes the present invention, is

illustrated and claimed in Letters Patent of the United States No. 422,000, granted to me February 25, 1800. The mechanism of said cigar-bunching machine shown in said Patent No. 422,000 is not elaimedlierein, but is illustrated with a view of explaining the construction and operation of the feeding mechanism sought to be protected hereby. It will therefore be unnecessary to specifically describe said cigar bunchingmachine proper, except in such respects as it maybe necessary so to do in order to render the description of the feeding mechanism definite and certain.

Referring to the bunchingmachine apart from the feeding apparatus, A designates the bed-plate or table of the machine, mounted on legs B, of suitable form and construction. Below the bed-plate is suspended in hangers C C the fulcrum-shaft D, and at the rear of the machine is journaled in suitable bearings the driving-shaft F, to which power may be applied by the usual band-wheel, and which will be regulated in its motion so as to stop and start as required by the customary clutchbox. (Not shown.)

The band-wheel and clutch-box mechanism for applying power to and regulating the stopping and starting of the driving-shaft F is well known in this class of machines and is in common use. An illustration of the mechanism for applying power to and regulating the motion of the driving-shaft F may be found in my aforesaid patent, No. 422.000.

Upon the bed-plate A is the rolling-table G, which will be provided with the usual apron, held at each end, .the bunch-receiver H, and a reciprocating roller I, mounted on the shaft J for rolling the bunch. Above the bunch-rolling mechanism is located an anxiliary table K, having an elongated opening L through it, as shown in Fig. 3, while above this opening L is arranged the series of reciprocatin g and independently-yieldin g pressers M for pressing the charge of tobacco through said opening L into the charge-receptacle N, bywhieh it is conveyed to the rolling mechanism, all as described in said Patent No. 422,000. As also fully pointed out in. said Patent No. 422,000,. there is a knife e" below the auxiliary table K, which knife (shown. by dotted lines in Fig. 3)v serves, when the pressers M are depressed, to sever that portion of the tobacco within the receptacle N from. the portion thereof above said receptacle, as shown in Fig. 18, thus detaching or separating a charge of tobacco for a bunch from the mainbody of tobacco and leaving said charge within said receptacle N in position. to be thereafter conveyed to the bunchrolli'ng mechanism.

Upon. the left-hand end of the table A is secured thev standard a, which supports the plate I), the latter having a rib on its under side to entera groove on the upper end of the standard, as shown by dotted lines in Figs. 1 an.d.7, whereby said plate I) may receive an adjustment, as hereinafter described, in a longitudinal direction toward or from the center of the machine.

Upon the plate b are mounted on vertical axes the belt-wheels 0 cl 6 f, (see Figs. 3 and 8,) the wheel a being provided at its annular center with the series of pins '7; and along the periphery of its upper and lower flanges j with the series of pins m, the latter to engage the apertures n in the upper and lower edges ofthe endless belt 6, as shown in Figs. 7 and 8, which belt, as shown particularly in Fig. 8, travels on the wheels d, e, f, and c, and receives its movement from the wheel 0. Upon the wheel 0 being rotated the pins m thereon engage the apertures 02 in the belt t and cause the{ latter to travel on its wheels. It should be noted that the belt 75 comes into contact with the belt-wheel 0 only at the edges of the upper and lower flanges j, and hence, that. a definite space is left between the main body of said wheel 0 and the moving belt I, as shown. in Figs. 7 and 8, through which space the surplus tobacco is carried, as hereinafter described. The plate 1) extends inward to a point close against the vertical side of the upper portion. of the bunching-machine proper and supports at opposite sides of the belt wheel 0 the belt-wheels lettered g h, respectively, the former of which, as illustrated in Figs. 3 and 8, is mounted on a spindle which passes through a slot in the said plate I), and is provided with a nut at its upper end, by which the spindle may be tightened at any desired point in the said slot, the purpose of said slot and nut being to regulate the adjustment of the wheel g, and thereby tighten or slacken the belt w, which travels thereon. The belt 10 travels over the wheel g at the left-hand end of the machine and over the belt-wheel oc,- located at the right-hand end of the machine, as illustrated more clearly in Fig. 3', said wheels g 00 and belt w being at the rear side of the machine. The spindle of the wheel w is also, like the wheel g, rendered adjustable by passing through an elongated slot, as shown in 3, in the customary manner known to mechanics.

The belt-wheel h is-connected with the beltwheel 3 by means of the endless belt-a, which; hasa traveling movement over said pulleys.

c, which moves upon the wheel 0 and wheel d. The right-hand portion of the belts-c and a. are

deflected outward in opposite directions-from the longitudinal center of the feed-trough-e, as shown in Fig. 3, in order that the tobacco- I as it is carried along said trough e, ashereinafter described, may be moved together at opposite sides by the converging walls of the facing sides of the belt a, c and then carried between that portion of the said belts at l the left of the pulleys b and f, the facing sides of which portion of the belts are parallel with each other ,,as illustrated in the drawings. The left-hand portion of thebelts a c at their facingsides travel one on each side of the opening L, formed in the auxiliary table K,

and said facing sides of said belts form an upward extension of the walls of said opening ;to receive the body of tobacco and permit its compressionthrough said opening L by the series of yielding pressers M, the surplus tobacco being carried along by the belts. The belt 0' maybe tightened, so as toremain taut on the wheels, by means of the adjustingscrew 0 and locking-nutP. The screw O-extends through. an internally-threaded aperture in the lug Q, extending downward from the plate 12, as shown in Fig. 7, and the point of said screw has abearing against the standard Ct. By adjusting the'sorew O itisobv-ious that the plate I) may be moved longitudinally on the standard a and be made thereby to cause the wheel 0 to draw the belt 0 taut.

The feed-trough 6 consists of a metallic elongated box supported upon the upper end of the vertical bracket 9 and sustained by the brace-rods h, the said box having it's-bottom covered by the endless traveling belt i and its sideslfor nearly its entire length covered bythe endless traveling belts j k", the purpose of the belts 2" j It" being to impart to the trough e' moving surfaces, which during the operation of the machine will carry the tobacco to its point of compression between the facing sides of the belts ct 0 above the elongated opening L. The belt t" moves upon the wheels Z and m, (shown more clearly in Fig. 1,) the belt j moves upon the wheels n and o, and the belt 7t moves upon the wheels 19 and q, the walls of the trough c being cut away suificiently to permit the edges of the wheels supporting said belts to project inward sufficiently to allow the facing sides of the beltsj 7a to be within the said trough e.

The wheels 11, p, 0, q, d, and y are provided with the series of pins 1", similar to the pins 1', (shown enlarged in Fig. 7,) to engage the series of apertures in the belts 0, ct, 7a, and j, (shown in Fig. 1,) arranged along the longitudinal center of said belts.

I will now describe the mechanism by which motion is imparted to the wheels (Z, q,o, and y and moving belts by which the tobacco is fed to the point of its compression below the series of pressers M.

Upon the driving-shaft F is secured the cam R, which during its revolution is caused to come in to contact with the roller S, secured to the lower end of the rocking lever T, pivotally secured to the outer end of the bracket V, (see Figs. 3 and 5,)the upper end of said lever T carrying the pawl \V in position to engage the teeth of the ratchet-wheel X, as shown by dotted lines in Fig. 5. The roller S is secured upon the pin Y, which is adjustable in the elongated slot Z, for the purpose of regulating the stroke of the lever T. The ratchetwheel X is mounted upon the auxil' iary drivingshaft A, which is supported in journals at the outer end of the bracket-arms B B, as shown in Fig. 3, and the upper portion of the rocking lever T has an elongated slot (shown by dotted lines in Fig. 5) which incloses said shaft A and limits the movement of the said lever in a well-known manner. The purpose of the cam R, rocking lever T, pawl IV, and ratchet-wheel X is to effect the rotation of the shaft A from the drivingshaft F and through said shaft A and its connected gearing to impart from the drivingshaft F the proper movements to the belts and other operative elements, as hereinafter pointed out.

Upon the shaft A is secured the beveled gear-wheel C, (see Figs. 3 and 5,) which meshes with the beveled pinion-wheel D, mounted upon the outer end of the transverse shaft E. The shaft E extends transversely beneath the feed-trough c, as shown more clearly in Fig. 5, and is supported in extensions from the vertical bracket 9.

Upon the shaft E is secured the sprocketwheel F, which is connected by a chain G, as shown in Figs. 2 and 3, with the sprocketwheel H, secured upon the outer end of the shaft 1, carrying the wheel in, which supports the inner end of the belt '6, constituting the lower surface of the trough 0. Upon the front end of the transverse shaft E is secured the beveled pinionwheel J, which meshes with the similar pinion-wheel K, mounted upon the lower end of the vertical shaft L, which carries the belt wheel 'y, located at the right-hand end of the traveling belt a.

Upon the upper end of the vertical shaft L is secured the gear-wheel M, which meshes with the intermediate pinion N, the latter engaging the pinion O and also the gearwheel P, which is secured on the upper end of the shaft Q, carrying the belt-wheel 0, located at the left-hand end of the traveling belt j. The gear-wheel O engages the gearwheel R, secured upon the upper end of the vertical shaft carrying the belt-wheel d, and the gear-wheel S upon the upperend of said shaft of said wheel 61 engages the pinion T, which is on the upper end of the belt-wheel a", carrying the belt 2c. The gear-wheel 0 also engages the gear-wheel V, secured upon the upper end of the shaft carrying the beltwheel (1, as shown by full lines in Fig. 2 and by dotted lines in Fig. 3. It will be seen that the motion communicated to the shaft E from the auxiliary driving-shaft A and beveled gear-wheels C D is imparted through the beveled gear-wheels J K to the gear-wheels M, N, O, P, R, S, and T, and is by these gear-wheels communicated to the belt-wheels 0, d, g, and m, which belt-wheels impart their motion to the traveling belts c, a, w, in, j, and t", the effect of the movement of the said belts being to convey the tobacco inward along the trough e, as hereinafter described. The movement from the auxiliary shaft A to the transverse shaft E has the effect also of rotating the sprocket-wheel F and, through the chain G, of causing the revolution of the sprocket-wheel II and shaft I, the end of which shaft is connected through the intermeshing gear-wheels IV, as, Y, and Z with the-transverse shaft a, as shown in Fig. 4. The shaft a extends transversely across the upper portion of the trough e, as shown in Figs. 2 and 3, and carries at about its center the resser-wheel b, which has a revolving movement imparted to it through the said gearing connecting the transverse shaft I with the transverse shaft to above described. The bottom of the trough e is provided with an elongated opening 0 (see Figs. 2, 4, and 6) to admit the edge of the wheel I) and the portion of the belt L" pressed therein. by the said wheel I), as indicated in the drawings. The elongated opening 0 is shown in cross-section in Fig. 6,and its length is illustrated in Figs. 2 and 4. The purpose of the presser-wheel I)" will appear hereinafter.

In the operation of the invention, motion being imparted from the driving-shaft F to the auxiliary shaft A and connecting mechanism, as above described, the leaves of tobacco for the fillers are placed lengthwise in the trough c, overlapping each other, as

lie

shown in Fig. 14:, and carried by the belts 'i', j, and k beneath the transverse plate (1. Thence said leaves are moved between the converging facing sides of the belts a and c to the opening L in the table K, where at regular intervals the tobacco is compressed by the pressers M and forced through the opening L into the charge-receptacle N, that portion of the tobacco within the charge-receptacle N being severed from the portion thereof above said receptacle by the act-ion of the knife 6", (shown by dotted lines in Fig. 3,) the surplus tobacco continuing its movement between the facing sides of the belts to and 0 until caught between the belts c andt after having passed beyond the contact of the belt a. The surplus tobacco after having passed beyond the belt a, is carried around the roller 0, between the belts c and t, and thence continued in its movement between the belts c and w, which carry said surplus to a convenient point of discharge. The traveling belts have imparted to them an intermittent motion through the medium of the pawl W and ratchet X, and hence the feeding of the tobacco may be regulated with a due regard to the operation of the pressers M.

In feeding the leaves to the trough e no particular care is necessary, except that it is desirable, in order to obtain the best results, that the leaves be spread out lengthwise in the trough with their edges and ends overlapping each other and with the body of tobacco of about an even thickness or depth. 7

The body of tobacco before reaching the elongated openingL passes beneath the wheel I)", which has a narrow edge, and depresses the traveling body of tobacco along its longitudinal center, and thereby effects the turning up of the edges of said body of tobacco, which in that condition is carried onward between the converging facing sides of the belts co 0', and thence to the elongated opening L, as shown as clearly as seems possible by a line-drawing in Fig. 1b, which represents in cross-section the relative positions of the tobacco, the knife e, pressers M, and charge-receptacle H. WVhen the knife e is beneath the open,- ing L, as shown in Fig. 16, the pressers M are in their elevated position; but upon the descent of the pressers the said knife will turn from beneath the said opening L and permit the pressers M to force the tobacco through said opening and into the charge-receptacle H, as shown in Fig. 17, whereupon the knife 'e" will sever the surplus tobacco, as shown in Fig. 18, and the receptacle H will convey the charge to the bunch-rolling mechanism, while the pressers M again ascend and the traveling body of tobacco moves onward between the belts, bringing a fresh portion of said body over the opening L and carrying away the surplus.

The position of the wheel 1) with relation to the elongated opening 0 is illustrated in Figs. 2 and 6, in which it will be observed that the edgeof the wheel is capable of depressing the belt t" along its longitudinal center as said belt moves beneath it, and hence when the tobacco-leaves are carried along by said belt in a moving body or layer the wheel I) will depress them along the center of said belt i, and thereby effect the turning up of the edges of the body or layer of leaves, as above described.

The feed apparatus constituting the invention may be successfully employed in the manufacture of scrap and short-filler cigars as well as for long-filler cigars, and hence it is'to be understood that I do not confine the invention to the feeding of unbroken leaves of tobacco placed lengthwise upon the belt 1'.

By extending the trough e a suitable distance to the right of the machine proper, as illustrated in Fig. 1, the attendant is given suflicient time to conveniently keep the trough upper portion of the trough e and serves to keep the tobacco down while entering between the converging facing sides of the belts to c, and said plate c constitutes also the lower portion of the box inclosing the gearwheels, by which motion is communicated to the wheels (1', g, y, and 0, the top of the box covering said gearing being forined'by the plate f By providing the tobacco-carrying belts with the seriesof holes to engage the pins on the belt-wheels I secure perfect uniformity of movement in said belts, preventing any slipping in the latter or any one or more of them and insuring the regular operation intended.

Referring to Figs. 9 to 13, inclusive, 66" designates a roller mounted in bearings b', each of which consists of a plate having an elongated slot to receive the end of the shaft of the roller 66"" bearings being secured to opposite sides of the feed-trough e and provided with flanges 0"" at their upper ends. The shaft of the roller a has a downward tension imparted to it by means of the spring-rods d, which pass through apertures in the flanges 0" and carry at their lower ends the insulating material e"", as shown enlarged in Figs. 12 and 13, which insulating material bears upon the shaftf" of the roller a". One of the spring-rods c is connected by a .wire 9" with an electric battery and is adjacent to the threaded rod 71", secured in a threaded aperture in the flange 0. The threaded rod h has upon its upper end the wheel or head 'i" which is connected with the electric battery by means of the conducting-wire j" and is insulated from the rod h". The

lower end of the. rod h is pointed,as shown, so as to be capable, when depressed, of entering between the teeth of the gear-wheel m", secured upon the end of the shaft f". l

, as shown in Fig. 10, said In the operation of the devices illustrated Ill Figs. 9 to l3,inclusive, the elevation of the roller 0 is effected by the tobacco passing along beneath it within the trough e, and the roller performs two functions, one being to preserve the tobacco in compact condition upon the lower belt of the feed-trough 6, while the other is to cause an alarm in case too much tobacco is being fed to the said trough. Upon an undue quantity of tobacco being fed to the feed-trough c the effect will be that the roller a will be elevated sufficiently to cause the teeth of the wheel m to engage the lower pointed end of the threaded rod 7W", under which condition the rotation of the roller (0 would cease and retard the passage of the tobacco along the trough to a definite degree. If, however, the attendantshould continue to feed tobacco to the trough, not observing the fact that the roller a had ceased to rotate, the further upward passage of the roller a would bring the upper end of the spring-rod against the rim of the wheel or head "17" and establish the electric circuit,which would include an alarm, the latter being sounded by the completion of the circuit and notifying the attendant a second time that too much tobacco was being fed to the trough e. The teeth of the wheel m', lightly engaging the lower pointed end of the rod h would cause the roller a to cease rotating; but this engagement of the said rod with said wheel would not of itself establish the electric circuit, since at such time the upper end of the spring-rod d would be close to but not in actual contact with the wheel or head i. As soon, however, as the tobacco in the trough should force the roller of and gear-wheel m upward sufficiently to cause the lower end of the rod h to enter entirely between the teeth of the wheel m" this additional upward movement would bring the upper end of the rod (Z" into contact with the wheel or head W", and thereby make the circuit and sound the alarm. It will be observed that the rod 71 maybe adjusted vertically so as not to interfere with the gear-wheel m until an undue quantity of tobacco had been fed to the trough e, and hence that the quantity of tobacco for the different sizes of cigars will determine the point at which the said geanwheel and rod should engage each other. lhe electric battery and alarm-bell in the circuit with the wires 9 and j are not illustrated, since they are of the usual well-known forms in general use and on sale for various purposes. \Vhen the roller 0 has been elevated, so that the gOiPWhGGl m engages the lower end of the rod said roller has a tendency to sweep the tobacco backward; but of course it will be apparent that if the trough c is forced with tobacco by the attendant not recognizing the fact that the roller a has ceased to rotate the slight further upward movement of the roller 0" which will be permitted by the depth of the teeth of the gear-wheel. m will cause the alarm to ring continuously until the tobacco has been withdrawn from beneath the roller (t and the upper end of the spring-rod relieved from contact with the head or wheel t" upon the upper end of the rod 72 The devices illustrated in Figs. 9 to 13, inclusive, aid in the formation of bunches of uniform size and density, and also prevent such an undue quantity of tobacco being fed to the machine as might destroy its functions or fracture some of its parts.
